Troubleshooting
Problem Solution
The air conditioner does
not work at all.
• Check the power status, then operate the air conditioner again.
• Switch on the circuit breaker, plug in the power cord, then operate the air
conditioner again.
• Make sure that the isolator is turned on.
• Check whether the Timed off function is running. Operate the air conditioner
again by pressing the Power button.
I cannot change the
temperature.
• Check whether the Fan or Fast mode is running. In these modes, the air
conditioner controls the set temperature automatically, and you cannot
change the set temperature.
Cool or warm air does
not come out of the air
conditioner.
• Check whether the set temperature is higher in the Cool mode or lower in the
Heat mode than the current temperature. Press the Temperature button on
the remote control to change the set temperature.
• Check whether the air filter is blocked with dirt. If the air filter is blocked, the
cooling and heating performance may decrease. Remove dirt regularly.
• Check whether the outdoor unit is covered or installed near obstacles.
Remove the coverings and obstacles.
• Check whether the air conditioner is running the defrost function. When ice
forms in winter or the outdoor temperature is too low, the air conditioner runs
the defrost function automatically. While this function is running, the indoor
fan stops and warm air does not come out.
• Check whether doors or windows are open. This may cause poor cooling or
heating performance. Close the doors and windows.
• Check whether the air conditioner is turned on immediately after the cooling
or heating operation stops. In this case, only the fan runs to protect the
outdoor unit compressor.
• Check whether the pipe length is too long. When the pipe length exceeds the
maximum pipe length, the cooling and heating performance may decrease.
I cannot change the air
flow direction.
• Check whether the good'sleep function is running. While this function is
running, you cannot control the air flow direction. (But you can control the air
flow direction if this function is running in the Heat mode.)
